CAIDA’s Annual Report for 2006

June 28th, 2007 by kc

CAIDA’s 2006 Annual Report covers last year’s efforts, summarizing highlights from our research, infrastructure, and outreach activities. Our current research projects, primarily funded by the U.S. National Science Foundation (NSF), include several measurement-based studies of the Internet’s core infrastructure, with focus on the health and integrity of the global Internet’s topology, routing, addressing, and naming system. Our infrastructure activities, funded by NSF and DHS as well as other government and industry sources, include building a catalog of Internet measurement data sets, contributing to the (DHS-funded) PREDICT repository of datasets to support the (U.S.-based) network research community, and developing and deploying active and passive measurement infrastructure that cost-effectively supports the global Internet research community. We also lead and participate in tool development to support measurement, analysis, indexing, and dissemination of data from operational global Internet infrastructure. Finally, we engage in a variety of outreach activities, including web sites, peer-reviewed papers, technical reports, presentations, blogging, animations, and workshops. CAIDA’s program plan for 2007-2010 will be available in July 2007.

Following Up On ‘A Day in the Life of the Internet’ Challenge

June 20th, 2007 by kc

[okay, that took about four times as long as i’d hoped, but we’re done with a preliminary cataloging of the data collected for our “Day in the Life of the Internet” experiment for 2007. -k]

As a refresher, this is a follow-up to our last year’s announcement that we would try out this experiment recommended by a National Academy of Sciences workshop, specifically, to capture ‘a day in the life of the Internet’ (DITL) to support the needs of network research. We believe the research community now has more measurement data (indexed!) than ever before about a single day of the Internet, and while the data situation is still pretty bleak, a little data is better than even less. In terms of measurements executed, we did significantly better than our practice DITL run in 2006, so there is cause for optimism about the future of this kind of experiment. As the summary makes clear, this year’s progress was mostly due to contributions from outside the U.S., in particular from Korea and Japan, countries which have generally more successfully navigated data sharing issues for their research communities than the U.S. has. We are sorry to say we did not index a single trace from a commercial provider link this year, although we were pleased to get participation from 5 of the 13 root nameserver anycast cluster operators, up from 3 last year.

If You Can’t Measure It, You Can’t Manage It

The following is an excerpt from a discussion forum for the Future of the Internet Workshop hosted by the Organisation for Economic Co-operation and Development (OECD), entitled “If you Can’t Measure It, You Can’t Manage It”. Tom Vest and KC Claffy, Cooperative Association for Internet Data Analysis (CAIDA).

1. The Internet is now a critical infrastructure and a global platform for communication and commerce. What should be the role of governments in its development and management?

A Day in the Life

September 4th, 2006 by kc

In 2001 the U.S. National Academy of Sciences convened a workshop to assess the state of networking research, and, in pursuit of objectivity and fresh insights, arranged for more than half of the attendees to be from other fields, in this case computer science. Among the most memorable conclusions:
